Rules

• react-doctor/effect-listener-cleanup-reference-mismatch

  Removal APIs match by reference identity, so the second inline function passed to the remove call can never equal the one you added; hoist the handler into a single named const (or useCallback) and pass that same reference to both the add and remove calls.

  No fix No autofix ↗
• react-doctor/effect-observer-needs-disconnect

  Return a cleanup function that calls observer.disconnect() (or observer.unobserve(node)) so the observer stops firing callbacks against detached nodes after unmount instead of leaking on every mount.

  No fix No autofix ↗
• react-doctor/effect-raf-loop-needs-cancel

  Store the frame id and return a cleanup that calls cancelAnimationFrame(id) so self-scheduling work cannot continue after unmount.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/expo-no-non-inlined-env

  Read env vars with static dotted access (process.env.EXPO_PUBLIC_NAME). Computed access and destructuring aren't inlined by babel-preset-expo and resolve to undefined at runtime.

  All repositories warning · 1 : warning in React Native projects
  No fix No autofix ↗
• react-doctor/firebase-client-owned-authz-field

  Derive authority fields on the server or enforce them in Firebase/Supabase rules; never trust client-provided owner, org, or role values.

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/firebase-permissive-rules

  Bind every read/write to request.auth.uid, immutable ownership, and tenant membership instead of treating sign-in as authorization.

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/forbid-dom-props

  Configure blocked DOM props so plain HTML tags stay on the agreed DOM API surface.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/forbid-elements

  Configure blocked elements so code stays on the approved UI primitives.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/forward-ref-uses-ref

  Accept the ref parameter or drop forwardRef so parents are not promised a ref that never reaches the node.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/git-provider-url-injection-risk

  Validate owner, repo, org, and branch identifiers against strict slugs and build URLs with URL/path encoders instead of raw interpolation.

  No fix No autofix ↗
• react-doctor/heading-has-content

  Put readable text in every heading.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/html-has-lang

  Set <html lang="…"> so screen readers know the page language.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/html-label-has-single-control

  Associate each label with one native control; use fieldset and legend to name a group of controls.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/html-no-invalid-paragraph-child

  Swap the <p> for a <div>, or move the child outside the paragraph.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/html-no-invalid-table-nesting

  Put each table element in its required parent: <thead>/<tbody>/<tfoot> directly inside <table>, <tr> inside a row group, <td>/<th> inside <tr>. Browsers quietly fix broken table markup, so write it to spec.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/html-no-nested-form

  Keep forms separate, or make the inner action a button associated with the outer form. HTML does not permit form descendants inside a form.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/html-no-nested-interactive

  Move the inner control beside its interactive ancestor so each action has independent semantics and focus behavior.

  No fix No autofix ↗
• react-doctor/iframe-has-title

  Add a descriptive title so screen reader users know what the embedded frame contains.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/iframe-missing-sandbox

  Add sandbox="" or a curated value so embedded pages cannot get full access to your site by default.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/img-redundant-alt

  Do not put 'image' or 'photo' in alt text. Describe what is shown.

  All repositories warning · 1 : warning in React projects
  No fix No autofix ↗
• react-doctor/import-metadata-execution-risk

  Parse imported metadata as data with strict schemas; do not evaluate EXIF, manifests, presets, dropped files, or archives.

  No fix No autofix ↗
• react-doctor/ink-ctrl-c-handler-requires-exit-option

  Pass {exitOnCtrlC: false} to render() before handling Ctrl-C with useInput.

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/ink-no-bare-process-exit

  Use Ink's useApp().exit() so Ink restores terminal state.

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/ink-no-direct-raw-mode

  Move useStdin().setRawMode() to an effect and restore it in cleanup.

  All repositories error · 1 : error in React projects
  No fix No autofix ↗
• react-doctor/ink-no-dom-host-elements

  Use Ink primitives such as <Box> and <Text> instead of DOM host elements.

• react-doctor/ink-no-dom-router

  Use React Router's memory router APIs in Ink applications.

  Measure Ink elements in a layout effect, effect, callback ref, or event handler.
